I've recently been experiencing problems with my MacPro when it goes into Sleep mode. It doesn't "wake up" or turn on again. My Energy Savings settings is that the display goes into sleep mode after 15 minutes & the computer after 3 hours. I'm also using the Apple Bluetooth mouse & my Bluetooth settings are that the computer should wake if a mouse button is pressed. Any tips or suggestions would be much appreciated. TIA. Edit: Forgot to mention that the only way I can restart the computer when it is in Sleep mode is to turn off the computer by pressing the power button for several seconds & then turning it on again by pressing the power button.
